Definitions
- the disclosure relates to pipe removal systems and methods and associated components thereof that include a washover tool for underground pipe removal.
- Pipelines are designed to transport products, such as sewage, water, or petroleum products, including oil and gas, between two different locations. These pipelines are typically steel or plastic tubes which may be buried underground. Processes and tools currently used in the art require craftsmen to sequentially dig up and cut out sections of the pipe from beneath the ground. Accordingly, these processes and tools used to remove these pipelines are extremely time consuming and often require highly skilled labourers, costly equipment, and dangerous conditions.
- Drilling machines utilize drilling rods or drill pipe that sometimes become stuck in the ground during the HDD process. When the drilling rods or pipe become stuck, in most cases, the rods or pipe are abandoned and a new pilot hole is created, because as stated above the processes and tools required to remove the suck rods or pipe are extremely burdensome.
- Implementations of the present disclosure relate to pipe removal systems, and methods of using pipe removal systems to remove underground pipes.

Description
- This application is a continuation of U.S. patent application Ser. No. 17/571,036, filed Jan. 7, 2022, which claims benefit of United States Provisional Patent Application Ser. No. 63/140,146, filed Jan. 21, 2021, which applications are herein incorporated by reference in their entirety.
- The disclosure relates to pipe removal systems and methods and associated components thereof that include a washover tool for underground pipe removal.
- Pipelines are designed to transport products, such as sewage, water, or petroleum products, including oil and gas, between two different locations. These pipelines are typically steel or plastic tubes which may be buried underground. Processes and tools currently used in the art require craftsmen to sequentially dig up and cut out sections of the pipe from beneath the ground. Accordingly, these processes and tools used to remove these pipelines are extremely time consuming and often require highly skilled labourers, costly equipment, and dangerous conditions.
- These pipelines are often installed using the Horizontal Directional Drilling method (or “HDD”). Drilling machines utilize drilling rods or drill pipe that sometimes become stuck in the ground during the HDD process. When the drilling rods or pipe become stuck, in most cases, the rods or pipe are abandoned and a new pilot hole is created, because as stated above the processes and tools required to remove the suck rods or pipe are extremely burdensome.
- Therefore, there is a need for a new and improved tools for underground pipe removal.
- Implementations of the present disclosure relate to pipe removal systems, and methods of using pipe removal systems to remove underground pipes.
- So that the manner in which the above-recited features of the disclosure can be understood in detail, a more particular description of the disclosure, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrate only typical embodiments of this disclosure and are therefore not to be considered limiting of its scope, for the disclosure may admit to other equally effective embodiments.

FIGS. 1A and 1B are top views of anouter housing 110 and aninner housing 120 of a washover tool 100 (more fully illustrated aswashover tools FIGS. 3A and 3B , respectively). When assembled, theinner housing 120 is positioned within theouter housing 110.FIG. 1C illustrates apipe 130 that can be washed over by thewashover tool 100 and removed from being buried underground. - The
outer housing 110 is a cylindrical pipe having an outer diameter d1 a, an inner diameter d1 b (illustrated inFIG. 2A ), and a length L1. The outer diameter d1 a may be within a range of 1.0 inches to 60 inches. The inner diameter d1 b (illustrated inFIG. 2A ) may be within a range of 0.90 inches to 59.9 inches. The length L1 may be within a range of 0.2 feet to 50 feet. Anupper opening 115 is formed through atop side 117 of theouter housing 110. Theupper opening 115 allows theouter housing 120 to receive a fluid, such as wash water, for washing over thepipe 130 as further described below. - The
inner housing 120 is a cylindrical pipe having an outer diameter d2 a, and inner diameter d2 b (illustrated inFIG. 2A ), and a length L2. The outer diameter d2 a may be within a range of 0.75 inches to 59.75 inches. The inner diameter d2 b (illustrated inFIG. 2A ) may be within a range of 0.65 inches to 59.65 inches. The length L2 may be within a range of 0.2 feet to 50 feet. In some embodiments, the length L1 of theouter housing 110 is the same as length L2 of theinner housing 120. In some embodiments, the length L2 of theinner housing 120 is greater than the length L1 of theouter housing 110. -
FIG. 1C illustrates thepipe 130 having an outer diameter d3 and a length L3, all or portions of which may be buried underground in a vertical orientation, a horizontal orientation, and/or at an angled orientation between vertical and horizontal. The outer diameter d3 may be within a range of 0.50 inches to 60 inches. The inner diameter may be within a range of 0.40 inches to 59.9 inches. The length L3 may be within a range of 1.0 feet to 5,280 feet. - The
outer housing 110 is larger in diameter than theinner housing 120. The difference in diameters of the outer andinner housings FIG. 2A ) between the two housing for receiving a high-pressure fluid, such as water or a drilling mud slurry, that flows out of thewashover tool 100. The actual diameters of the outer andinner housings adequate annulus 220 between the outer andinner housings inner housing 120 relative to thepipe 130 to be removed may depend on the ground conditions that thepipe 130 is buried or stuck in, but theinner housing 120 should be large enough to slip over thepipe 130 freely. The lengths L1, L2 of the outer andinner housings outer housing 110 is the same as length L2 of theinner housing 120. In some embodiments, the length L2 of theinner housing 120 is greater than the length L1 of theouter housing 110. - In operation, the
washover tool 100 is positioned circumferentially around thepipe 130 such that thepipe 130 extends through theinner housing 120. Thewashover tool 100 is moved along the length L3 of thepipe 130 while spraying a wash fluid to washover thepipe 130 to remove dirt, debris, and/or the ground surrounding thepipe 130. Thepipe 130 may be any type or size used to transport fluids, solids, and/or mixtures of fluids and solids, including but not limited to oil and gas. Thepipe 130 may also be any type or size of drill rod or drill pipe utilized by an HDD or road boring machine. -
FIG. 2A is a cross-sectional front view of only a portion of thewashover tool 100, according to one or more embodiments. Theinner housing 120 is positioned circumferentially within theouter housing 110. The inner diameter d2 b of theinner housing 120 is greater than the outer diameter d3 of thepipe 130, so as to allow thewashover tool 100 to be positioned around thepipe 130. The inner diameter d2 b defines thebore 250, in which thepipe 130 is located when thewashover tool 100 is used to washover thepipe 130. - The inner diameter d1 b of the
outer housing 110 is greater than the outer diameter d2 a of theinner housing 120, as to form anannulus 220 between theouter housing 110 and theinner housing 120. The difference between the inner diameter d1 b of theouter housing 110 and the outer diameter d2 a of theinner housing 120 determines the width of theannulus 220. The width of theannulus 220 may be within a range of 2 inches to 24 inches. The width of theannulus 220 may be large enough to provide sufficient fluid flow to washover thepipe 130. - The
outer housing 110 has athickness 215. Thethickness 215 of theouter housing 110 may be within a range of 0.10 inches to 2.0 inches. Additionally, theinner housing 120 has athickness 225. Thethickness 225 of theinner housing 120 may be within a range of 0.10 inches to 2.0 inches. In some embodiments, thethickness 215 and thethickness 225 are the same. In some contemplated embodiments, thethickness 215 and thethickness 225 are different. The thickness of theouter housing 110 and theinner housing 120 may be thick enough to allow proper welds to be made to assemble thewashover tool 100. - The
washover tool 100 further includes a plurality of centeringmembers 210 disposed between theouter housing 110 and theinner housing 120 to center the outer andinner housings washover tool 100 and theannulus 220. In some embodiments, the centeringmembers 210 are metal blocks welded to theinner housing 120 and theouter housing 110 and disposed within theannulus 220. The centeringmembers 210 may be radially spaced within theannulus 220 and may only extend along a portion of the length of the inner and/orouter housings -
FIG. 2B is a front view of only a portion of thewashover tool 100, according to one or more embodiments. Thewashover tool 100 includes afront face plate 230 that covers theannulus 220. Thefront face plate 230 is welded to an end or front surface of theouter housing 110 and to the outer surface of theinner housing 120 such that anouter edge portion 260 of theinner housing 120 extends from the outer housing 110 (e.g. the length of theinner housing 120 is longer than the length of the outer housing 110). In some embodiments, thefront face plate 230 may be welded to the outer andinner housings front face plate 230 covers the ends or front surfaces of the inner andouter housings 110, 120 (e.g. the length of theinner housing 120 is the same as the length of the outer housing 110). In some embodiments, thefront face plate 230 may be welded to the inner diameter of theouter housing 110 and the end or front surface of the inner housings 120 (e.g. the length of theouter housing 110 is longer than the length of the inner housing 120). - The
washover tool 100 may similarly include a back face plate, which is disposed at an opposite end ofwashover tool 100 from thefront face plate 230. The back face plate may be welded in a similar manner as thefront face plate 230. Together, thefront face place 230 and black face plate enclose theannulus 220 between theouter housing 110 and theinner housing 120. - The
front face plate 230 includes a plurality ofopenings 240 formed through thefront face plate 230, through which several jets or streams of wash fluid may flow through. Theopenings 240 may be radially positioned about thecenter axis 205 on thefront face plate 230. Thefront face plate 230 includesenough openings 240 to allow for adequate fluid flow through thewashover tool 100 to properly wash, loosen, and/or remove any material surrounding thepipe 130. For example, thefront face plate 230 may include between four and five hundred openings 240 (although any number, orientation, and/or arrangement ofopenings 240 may be used) formed through thefront face plate 230 radially about thecenter axis 205. Eachopening 240 may be drilled, or drilled and tapped to allow for threaded opening inserts to be installed into thefront face plate 230. Theopenings 240 and/or the threaded opening inserts may be sized to achieve a certain pressure of washover spray. For example, theopenings 240 and/or the threaded opening inserts could be between 0.0001 inches and 1 inches. Eachopening 240 and/or threaded opening insert could provide for an angle of spray between 0 degrees and 360 degrees. Eachopening 240 allows fluid supplied to thewashover tool 100 to spray from thewashover tool 100 over the buriedpipe 130. The wash fluid flowing out of the plurality ofopenings 240 washes over thepipe 130, thereby allowing thepipe 130 to be easily removed from the ground. -
FIGS. 3A and 3B are top views ofwashover tools rod member 320 and one ormore stabilization members outer housing 110, according to one or more embodiments. Therod member 320 is a cylindrical pipe having a fixed end 325, anelongated body 327 and a receivingend 329 opposite the fixed end 325.

In some embodiments, thewashover tools stabilization members stabilization members annulus 220 to be ejected from thestabilization members washover tools -
FIGS. 4A and 4B are side elevation views of thewashover tools rod member 320 and a plurality of fluid jets W spraying from thewashover tools washover tools elongated body 327 of therod member 320 and theouter housing 110. The rod member supports 410 provide additional support to therod member 320 to prevent lateral rotation of therod member 320 during operations. In some embodiments, the rod member supports 410 are the same length as the length L1 of theouter housing 110. In another embodiment, the rod member supports 410 are have a length less than the length L1 of theouter housing 110. The rod member supports 410 may be welded to both therod member 320 and theouter housing 110. - In some embodiments, the
elongated body 327 of therod member 320 is disposed on and coupled directly to theouter housing 110 as illustrated in thewashover tool 100 a ofFIG. 4A . Therod member 320 of thewashover tool 100 a has atapered end 420 so that therod member 320 is in contact with theouter housing 110 along the entire length L1 of the outer housing. Thecap 330 a is coupled to thetapered end 420.FIG. 4A further illustrates the alignment of theopening 115 of theouter housing 110 and the opening 315 of therod member 320. The alignment of theopenings 115, 315 provides for the fluid communication between therod member 320 and theannulus 220. Theopenings 115, 315 are axially aligned and are sealed together to form a single fluid chamber between theannulus 220 and the bore of therod member 320. - In some embodiments, the
elongated body 327 of therod member 320 is coupled to theouter housing 110 via aconnection member 450 as illustrated in the washover tool 110 b ofFIG. 4B . Theconnection member 450 is a cylindrical pipe with a bore formed therethrough. Theconnection member 450 may be axially aligned and formed within theopening 115 of theouter housing 110. The opening 315 of therod member 320 may be aligned with and coupled to theconnection member 450, so as to provide fluid communication between therod member 320 and theannulus 220 through theconnection member 450. Therod member 320 has one or more rod member supports 410 formed between theelongated body 327 and theouter housing 110 to provide support to therod member 320 during operation of thewashover tool 100 b. -
FIGS. 4A and 4B illustrate the plurality of fluid jets W being sprayed from thewashover tools washover tools annulus 220 by therod member 320. The pressurized fluid is then sprayed from theannulus 220 through the plurality ofopenings 240 in the form of fluid jets W along and/or about thecenter axis 205. The number of fluid jets W from thewashover tools openings 240 formed in thefront face plate 230. The fluid jets W washover thepipe 130. -
FIGS. 4A and 4B further illustrate thewashover tools outer edge 260 of theinner housing 120 extending past thefront face plate 230. In such embodiments, theinner housing 120 has a length L2 greater than the length L1 of theouter housing 110, such that theouter edge 260 andfront surface 265 of theinner housing 120 extend past thefront face plate 230. Thefront surface 265 and theouter edge 260 provide for additional ground removal during washover operations of thewashover tools inner housing 120 may extend past the back face plate such that theouter edge 260 extends past the back face plate. In some embodiments, the back face plate completely covers the rear or back ends of theinner housing 120 and theouter housing 110. -
FIG. 5 is a schematic side view of awashover system 500 in operation to remove thepipe 130 from theground 520, according to one or more embodiments. Thewashover system 500 includes thewashover tool 100 a (but may similarly include thewashover tool 100 b or any other embodiments of the washover tools described herein) and acontrol source 510. Thecontrol source 510 supplies the fluid, such as washover water to thewashover tool 100. Furthermore, thecontrol source 510 provides power to move thewashover tool 100 a along the length of thepipe 130 and into theground 520 by pushing on therod member 320. In some embodiments, thecontrol source 510 is configured to disconnect from thewashover tool 100 a and reconnect to thepipe 130 to remove thepipe 130 from theground 520 after thepipe 130 has been washed over with thewashover tool 100 a, and while thewashover tool 100 a remains on thepipe 130 The ability to disconnect and reconnect from thewashover tool 100 a and thepipe 130 without having to completely remove thewashover tool 100 a increases the efficiency and decreases the cost of the pipe removal operations by limiting the operation time normally associated with removing one or more tools from the control source and/or thepipe 130 before attempting to remove thepipe 130 from the ground. - The
rod member 320 of thewashover tool 100 connects to thecontrol source 510 to receive a fluid, such as washover water, from thecontrol source 510. As discussed, therod member 320 is coupled to thetop side 117 of theouter housing 110 so that theopening 115 of theouter housing 110 and the opening 315 of therod member 320 are aligned. The bore of therod member 320 and theannulus 220 are in fluid communication, allowing pressurized fluid to be supplied to thewashover tools control source 510. The fluid flows through therod member 320, into theannulus 220, and out of the plurality ofopenings 240 to washover thepipe 130. - The
washover system 500 removes thepipe 130 embedded in theground 520. Theground 520 may be any earth-like material, such as a sand or soft clay. Thepipe 130 may extend some distance into theground 520, thus requiring thewashover tool 100 a to be moved along thepipe 130 and into theground 520 to remove any earth material surrounding thepipe 130. As thewashover tool 100 extends farther into theground 520, additional pipe members may be fastened therod member 320 by thecontrol source 510 to provide continuous fluid communication between thecontrol source 510 and thewashover tool 100 a. As each additional pipe member is added to thewashover system 500, thecontrol source 510 supplies power to move thewashover tool 100 along the length of thepipe 130 by pushing the pipe members connected to therod member 320, while simultaneously providing pressurized fluid to washover thepipe 130. - The pressurized fluid is carried by the pipe members and the
rod member 320 into theannulus 220 and ejected from theannulus 220 through the plurality ofopenings 240 formed in thefront face plate 230. The plurality ofopenings 240 form a plurality of water jets W, which remove anyground 520 surrounding thepipe 130. The water jets W loosen theground 520 around thepipe 130 and allow thesource 510 to remove thepipe 130. - In some embodiments, the
outer edge 260 andfront surface 265 of theinner housing 120 removeadditional ground 520 surrounding thepipe 130 as they contact theground 520. As thewashover tool 100 is moved along thepipe 130, thefront surface 265 extending past thefront face plate 230 loosens theground 520 immediately surrounding thepipe 130. Simultaneously or after, pressurized fluid is supplied to thewashover tool 100 a to washover thepipe 130 and removeadditional ground 520 around thepipe 130. This process repeats along the length of thepipe 130 until thepipe 130, or a section thereof, can be removed from theground 520. -
FIG. 6 is a flow chart illustrating amethod 600 of using thewashover system 500, according to one or more embodiments.Operation 602 of themethod 600 comprises placing the washover tool (such aswashover tools pipe 130 extending into theground 520. Inoperation 602, the washover tool is placed around thepipe 130 at a location where a startingend 530 of thepipe 130 is exposed from theground 520. - At
operation 604, pressurized water is injected into the washover tool. The pressurized water is supplied from thecontrol source 510 through therod member 320, or through a series of additional pipe members coupled between therod member 320 and thecontrol source 510. Atoperation 606, the pressurized water is ejected from the washover tool through a plurality ofopenings 240 formed in the washover tool to washover thepipe 130. Duringoperation 606, the pressurized water may be continuously ejected from the washover tool until a requisite amount of theground 520 is removed from the area surrounding thepipe 130 while the washover tool remains in a stationary position. - At
operation 608, the washover tool is then moved along the length of thepipe 130 to washover thepipe 130 with the pressurized water to remove theground 520 surrounding thepipe 130. In some embodiments, thefront surface 265 of theinner housing 120 also removes theground 520 surrounding thepipe 130 as the washover tool is moved along the length of thepipe 130. - Finally, at
operation 610, thepipe 130 is removed from theground 520.Operation 610 includes disconnecting the washover tool system from thecontrol source 510 by decoupling therod member 320, or the series of pipe members coupled to therod member 320, from thecontrol source 510. Thecontrol source 510 is then coupled (such as by a threaded coupling) to the startingend 530 of thepipe 130. Thecontrol source 510 then applies a pulling force on thepipe 130 to remove thepipe 130 from theground 520.
